Abstract
The invention provides a brazing filler alloy and a preparing method thereof. The brazing filler alloy is composed of, by mass percentage, 50% of Mg, 0.8% of Al, 2% of Sn, 0.002% of Be, 0.3% of La, 5% of Bi and Zn as balance. The preparing method of the brazing filler alloy comprises preparing materials according to the mass percentage proportion above; heating melting the prepared materials into an electric furnace crucible with SF6 as the protective atmosphere; when the heating temperature is increased to 680 DEG C, performing heat preservation for 10 minutes and then pouring the molten materials into a ingot mould for cooling, which is preheated to 200 DEG C, to obtain the brazing filler alloy.
Description
Technical field
The present invention relates to the preparation method of a kind of solder alloy and this solder, belong to materials processing technology field.
Background technology
Solder refers to the combination for realizing bi-material or parts, betwixt the other added filler in gap or gap.The fusing point of solder must be lower than the material melting point of welding.Can be used for connecting accurate, complicated, the welding of seam and foreign peoples's material how quickly.Solder is divided into the soft solder solder of 450 ℃ (fusing point lower than) and the hard solder solder of 450 ℃ (fusing point higher than) by fusing point height.
At present, in existing magnesium alloy brazing filler metal and preparation thereof, there is the shortcomings such as cost is high, fusing point is high, processing performance is poor, the problem such as not good.
Summary of the invention
The present invention is directed to the defect that prior art exists, a kind of brazing filler metal alloy is provided, this brazing filler metal alloy spreadability is good, and weldering performance is good.
Another object of the present invention is to provide the preparation method of above-mentioned brazing filler metal alloy, and the method technique is simple, is suitable for industrialized mass.
The object of the invention is to realize by following measures:
A kind of brazing filler metal alloy, the quality percentage composition of its alloying component is: 55%Mg, 0.8% Al, 2%Sn, 0.002%Be, 0.3%La, 5%Bi, all the other are Zn.
Its preparation process is as follows:
First be 55%Mg according to quality percentage composition, 0.8% Al, 2%Sn, 0.002%Be, 0.3%La, 5%Bi, all the other are prepared burden for Zn, by above-mentioned prepare be placed on SF
6heat fused together in the electric furnace crucible of protective atmosphere, in the time that temperature rises to 680 ℃, is incubated and after 10 minutes, is poured in the ingot mould that is preheating to 200 ℃ coolingly, just obtains brazing filler metal alloy.
the present invention has following beneficial effect compared to existing technology:
Magnesium-based brazing filler metal alloy of the present invention, raw material is easy to get, and preparation technology is simple, and brazing filler metal alloy is functional.
In alloy, each element mainly plays the effect of following several respects:
In brazing filler metal alloy of the present invention, the fusing point of Bi and Sn itself is all lower, adds them can reduce the fusing point of brazing filler metal alloy.
The wetability that in composition, Bi can fine raising solder, can also more effectively improve the spreadability of material.
In the present invention, the composition of brazing filler metal alloy and welded magnesium alloy composition approach, and can improve the shear strength of welded alloy solder joint.
The specific embodiment
Embodiment mono-:
Each composition weight percentage is pressed 55%Mg, 0.8% Al, and 2%Sn, 0.002%Be, 0.3%La, 5%Bi, all the other are prepared burden for Zn.In its Raw, get pure Al ingot, pure Mg ingot, pure Sn bar, pure Be piece, pure Bi powder, the pure Zn bar of g, Mg-La intermediate alloy piece (wherein the quality percentage composition of La is 15%), is placed on SF
6in the electric furnace crucible of protective atmosphere, heat fused, in the time that temperature rises to 680 ℃, is incubated and after 10 minutes, is poured in the ingot mould that is preheating to 200 ℃ coolingly, just obtains brazing filler metal alloy.
experimental data:
Following table is the index parameter of the magnesium-based brazing filler metal alloy that makes of the present invention, specific as follows:
| Material | Shear strength (Mpa) | Spreading area (mm 2） | Soldering operating temperature (℃) |
| The material making as embodiment mono- | 70 | 182 | 395-405 |
